This rear-wheel-drive off-road buggy boasts a midship layout, placing the motor just ahead of the rear wheels for optimal weight distribution and agility. The high-rigidity duralumin main chassis has been subtly modified, carrying over the proven low-profile gearbox and other key components from the Ultima RB7 for a refined driving experience.

The new body, based on the superb aerodynamics of the RB7, features design modifications to the rear cabin for even greater efficiency. The rear wing has also been completely redesigned for increased strength, generating powerful and stable downforce for enhanced high-speed stability and control.

The front and rear shock towers have been upgraded from plastic to 4mm thick carbon fibre, significantly increasing strength and rigidity. These new towers offer better protection during rollovers. New aluminium oil shocks with 13mm pistons further enhance stability at high speeds and over uneven surfaces, effectively absorbing landing impacts, with improved springs for superior performance.

For a direct and responsive connection to the track, the Ultima RB7.5 utilises an aluminium steering crank and plate. This setup offers high rigidity and smooth operation, translating your inputs into precise wheel movement. The redesigned upper bulkhead ensures trouble-free servo horn operation.

The Ultima RB7.5 offers a highly tunable rear suspension. The redesigned aluminium hub carriers allow for upper rod length adjustments and increased bearing support, while the new rear bulkhead with a separate upper rod mount enables precise changes to the suspension geometry for maximum grip and stability.

The addition of the centre bulk support significantly increases the rigidity of the chassis, resulting in improved traction and more consistent handling, particularly when accelerating out of corners. This enhanced stiffness provides a more planted and predictable feel, allowing you to carry more speed through turns.

The LCG battery mount allows for convenient forward-back weight distribution adjustments, featuring a tool-free, one-touch system for quick battery installation and removal. This makes it easy to fine-tune the buggy's handling characteristics to suit different track conditions and driving styles.

The previously optional front wing is now included as standard, providing an effective tuning part to adjust the buggy's aerial posture during jumps. It also influences cornering characteristics, allowing you to fine-tune the front-end grip and overall handling to your preference.
